BEINFORCED CAR-WALL CONSTRUCTION.

Be it known that I, OsoAR HooHBuRG, a

citizen ofthe United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful' Improvement in Reinforced Car-Wall Construction,

of which the following is a full, clear, and

exact description, such as will enable others skilled in the art to which it appertains to .make and use the same, reference being. had to the accompanying drawings, forming part of this specification.

Thisy invention relates to railway car coni struction, and particularly to a wall ,con-

struction for freight car l Inasmuch as the provision of str o'ngfecofreight cars is of exceptional importance,

I due to the stresses to which said walls are membersiassociated. with the wall, it is neces- 'sary to provide insuch a structure major stiifening i" reinforcing members which operate' to strengthen the structure as an entity, particularly at points removed from the car framing members, and to give the structure the stability necessary to enable it to withstand heavy or repeated cargo thrusts.-

At the same time, there are certain limitations which must be observed, particularly in weight, cost, and dimensions. The importance of the two first mentioned limital tions is obvious, and the last mentioned will be recognized as of great importance 'par`1 ticularly with respect to the maintenance of l proper clearance between the wall -strutture and associated parts, such as the brake shaft, coupler operating levers, gra:` irons, door haners and the like.

e purpose of my present invention is directed particularly to the provision of a wall structure wherein a maximuwmvstrength li'siobtained at the necessary "peints with the use of a minimum amount of material, and wlthout encroachment upon the lirmts of the proper inside and outside clearances.

cars, it is neceary to provide either a horizontal or vertical reinforcement along the median line, so as to stiffen the structure across its. entire extent, and to transmit thrusts received at such portions to the heavier framing members adjacent the margins of the wall. .In the illustrative disclosure herein shown, the median reinforcement is disposed horizontally in the end structure. Figure 1 is a front'elevation of the end structure. v

Fig. 2 is a horizontal section on line 2-2 of Figi 1.

Fig. 3, a vertical section on line 3-,3 of

Fig. l. nomical and easily repaired end 'walls in Fig. 4t, 'a detail showing the construction at one end of the median reinforcement, portions being broken away.

Fig. 5 is a similardetail showing a modilied arrangement.

The end structure as shown' includes an upper panel of sheet metal 1 and a lower sheet metal panel 2, each of which extends intermediate the corner posts il. These sections may be provided with corrugations 5' pressed therein and extending transversely thereof. The lower section 2 is secured to the end sill 6 and the upper section is secured to the end plate 7. The adjacent edges of the 'upper and lower sections overlap as best illustrated in Fig. 3, and a reinforcing member is interposed between the overlapping margins.

This reinforcing member is a strip of sheet metal exceeding somewhat in length the length of the sections 1 and 2, and it has pressed therein longitudinally extending corrugations 9 and 9a. These corrugations are pressed in opposite directions, so that one protrudes from one face of the reinforcing member and the other protrudes from the opposite face. When assembled with the sections l and 2, the overlapping margins of the sections lie intermediate these longitudilnal corrugations 9 and 9a, and fastenings 10 are seated in the overlapping margins of the sections and the interposed portion of the rcinforcing member, so asto secure the three portions firmly together along substantially the median line of the end wall. The lower portion of theupper section 1 may be slightly offset, as at 13, to accommodate the thickness of the upper portion of the reinforcing member 8, and the latter member,

adjacent its upper margin, is secured to the upper section by a line of fastenings 11. In similar fashion the lower half of the reinforcing member overlaps on the exterior of the lower section 2, and adjacent its margin is secured thereto by a line of fastenings 12.

The endlmargins of the sections 1 and 2- are turned rearwardly to provide flanges 14, which overlap the corner posts or the side walls, and are secured thereto by a line of bolts. In similar fashion the extremities of 'the lower half of the reinforcing member 8 l posts or side walls, and are secured thereto by bolts 17. The reinforcing member, of course, is slotted longitudinally at its extremities to permit the {lang-ing of the upper` portion short of the lower portion. If desired, the entire extremity of the reinforcing member may be carried to the outside of the corner posts, as illustrated in Fig. 5. In the manner ust described, the extremities of the reinforcing member are firmly anchored to the car superstructure `and framing members, and of course, any suitable tie members may be added to connect the flanged extremities of the reinforcing member to other framing portions. If an inside sheathing is desired, a nailing strip 18 may be arranged in contact with and below or above the internal coriv 'gation 9, and secured to the end wall by bolts 19. Inside sheathing 20 may then be secured to the nailing strip in the customary fashion.

By virtue of the construction above described, the wall is provided with a very eifective median reinforcement extending the entire width of the end and secured at its extremities .to the heavy framing members. This reinforcing member in conjunction with the portions of the upper and lower sections which it overlaps, forms a beammember having an effective radius of substantially the aggregatedepth of the two corrugations 9 and 9, thc lower corrugation forming a tension member, with respect to cargo thrusts, and the upper corrugation forming a compression member. It will be observed that while the beam thus formed has a considerable radius, due to the relative internal and external disposal of the corrugations 9 and 9", the internal and external clearances of the end wall have not been altered to a point where the beam member will interfere with the mounting of the brake shaft, or with the placing of the inside sheathing or lining.

The corrugations 5 function in the-customary fashion to transmit thrust moments to the upper and lower framing members,

strength for its weight, and is economical in cost and durable in service. While I-have described the invention as applied'to a can end having the wall sections disposed one 5 above the other, it is obvious that the invenj tion may be embodied in a construction wherein the wall sections are disposed side by side, and the reinforcement extends vertically, in which position it functions not only as a beam for carrying stresses ex# erted transversely of the wall structure, but' also as a post for supporting loads acting in line with the wall structure.

, I am aware that the construction as illusp trated and described is susceptible ofv still further alterations, modifications and adaptations not specically referred to, but nevertheless comprehended within the scope and spirit of my invention as indicated in the following claims.

That I claim is:

1. A wall structure for railway cars comprising conjoined sheet metal sections and an interposed reinforcing member overlapping and secured to both of said sections and having corrugations extending longitudinally of the sections and protruding in opposite directions.

2.' A wall constructionv for railway cars comprising juxtaposed sheet vmetal sections and an interposed reinforcing member overlapping and secured to both of said sections and formed with corrugations extending longitudinally of the sections and protruding in opposite directions; said sections and said reinforcing member being secured at their extremities to car framing members.

3. In a wall construction for railway cars, a pair of juxtaposed sheet metal sections secured at their extremities to car framing members, and a reinforcing member interposed between the said sections and secured thereto; said reinforcing member being formed with corrugations extending longitudinally, one of which corrugations protrudes to the inside and the other to the outside of the car wall.

4. In a wall construction for railway cars, a reinforcing member secured at its extremities to car framing members and formed with collaterally disposed longitudinal corrugations protruding in opposite directions, and sheet metal sections secured at their margins to car framing members and to said reinforcing member. i
